This screams Iron Man 2 all over again, which was, imo, the worst Marvel movie post-well....Iron Man.
There was too much going on...Whiplash, Nick Fury, Black Widow, Justin Hammer, War Machine...even the action was not all that.

Now, this is the first solo Cap movie after being defrosted, which means this should be about him being accustomed to the 21st century.
To have Sam Wilson (not The Falcon) in the movie i can get, but to have the return of Bucky is waaaayyyy too much.
